ABSTRACT:
An improved intermediate transfer surface employing a conductive fluoropolymer material and preferably a conductive material dispersed in a fluoroelastomer layer is provided for use in electrostatic color image transfers. The intermediate fluoropolymer transfer surface is heat and solvent resistant and retains its electrical conductivity upon exposure to both heat and solvent, while exhibiting excellent thermal release characteristics for contact transfers of dried liquid color toners. A method of xeroprinting a color image onto a receiving substrate using a first electrostatic transfer through a liquid-filled gap to the conductive intermediate transfer surface and then a second contact transfer from the conductive intermediate fluoropolymer transfer surface to a final receiving surface is also disclosed.
